Specification of Letters Patent.

Patented June 30, 1908.

Application tiled Key 25, 1907. Serial No. 375,609.

To all whom it may win-mm:

Be it known that i. (f/Ami tbi'ri'mn, a citizen of the. German l hnpire, and resident of Steglitz, near Berlin, iiern'nm have invented certain new and useful improvements in Machines for Nailing lhe Uppers of Shoes to Soles of Wood or an Similar Material, of which the l'ollowing is a specification.

This invention has for its object a nailingmachine. intended ior fastening the uppers of shoes to soles ol wood or similar mu?" rial.

Compared with the shoe nailing nnichines now-"snown, in which the shoe with its edge, into which the nails are to be driven, is passed step by step. along a hammering or imiling(levice. the essential i'enture of the present invention consists therein that the nailinglevice is passed automatically around the fixed or stationary shoe, and thus drives the nails into it.

The invention is illustrated on the accompnnying drawin where I Figure I shows a eross-seetizm oi the machine with thecontrivance l'or advancing the nailing-device, Fig. :2 a longitudinal section on the line A---A oi Figv i, and Fig. 3 a cross section on the line iii) oi l i with the contrivance for turning the nailmgdievice.

Similar numerals reler to similar parts throughout the sweral views.

On the frame 1 ol the. machine lies a piste 2 with a surface 3, upon which the soles are laid, which plate is provided with a suitable clamping-device t for the soles of the shoes 5. In the plate 2 is provided a slide xvay 6 run ning parallelly around the shoe or its Form. The nailing-device itself mu y be. of any suitable kind. The same consis hero of a shaft 8 with a cam-disk 9, which moves the samper or mmmer 10 serving to press nails into the shoe, which is conslnntiy ad by a s )ring or the like agninst the GtUiMliz-ih.

the direction 25 and the chain 12, with the nailing-device 710, moves, step by step, in the direction 26. The distance of the nails from each other depends on the size of the said steps. The nailing is done by the nailingdev1cc each time the chain stops. i To bring about the nailing there is arranged on chain, and thereby the wneel 35 on the shaft- 8 of the nailinga'levice. The wheel 35 sits loosely on the shaft is and only moves the same in one direction through the coupling 36. This coupling is necessaryns, on account ol. the gradual forward translation of the shaft 8, the wheel 35 must be able to move in the toothed chain 34. r

When the device for moving the shaft 8 forward rests, the device for rotating the shaft 8 works. By a suitable proportion of the parts 3 1 and 35 the shalt 8 can be made to make a revolution'at each step.

'lhenmchine may, of course, be so constructed that different sizes of shoes can be nailed with it, without departing from the principle of the invention.

What I claim as my invention and desire to secure by United States Letters Patent is:

1. In a machine for nailing the upper parts of shoes to soles of wood or any similar materiol, a fixed plate with means for clamping the soles of the shoes and having a slideway, a nailing device, located in the slideway; means for operating the nailing device intermittently consisting of an endless chain (12) engaged with the nailing device; chain wheels over which passes said chnin; a shaft connected to one. oi the. chain-wheels and means For moving said sha'l't stop-lrv-step, substantially as described.

2. in a machine for nailing the upper parts oi shoes to soles oi" wood or any similar material, u 'lixed plate with menus for clamping the soles of the shoes and having a slideway, a nailing device, located in the slideway; menus for operating the nailing device in lermittently consisting ol an endless chain (12) engaged with the nail ng device; chain wheels over which passes said chain; a shai't connected to one or" the chainwvheels and means for moving said shaft step-by-step &- tocthed chain (34) in connection with the nailing device, a counter-shaft, a gear Wheel on said silaft engaging with said toothed chain. and another gear Wheel (30) on the same shaft, a driving shaft, an eccentric on said shaft and a link connected to the eccentrio and engaging with the gear Wheel (39) seep-i0 for rotating the latter stepwise, substaik 10 tieliy as describeii.

In testimony whereof I have signed my name to this specification in. the presence of two subscribing Witnesses.

CARL SATTLER.
